SELF-THREADING SHUTTLE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 411,403, dated September 17, 1889.

Application filed July 13, 1889.

To @ZZ 1072/0711/ it may concern,.-

e it known that I, n/[AXIME VIENooHE, a citizen of the United States, residing at lVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Self-Threading Shuttles for Looms; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable Io others skilled in the art to which it appertains to make anduse the same.

This invention has relation to improve- Inents in shuttles for looms; vand it has for its object the provision of means to facilitate the threading, as will be hereinafter more fully set forth, and particularly pointed ont in the claims appended.

In the accompanying drawings, forming part of this specification, Figure l is a longi- :o tudinal sectional view of a shuttle with my improvements applied, with the spindle and cop or bobbin in a raised position. Fig. 2 is a similar view of a shuttle threaded and ready for use. Fig. is a side View of a portion of a shuttle, showing the outside of the threading-plate and the thread in position ready for use. Fig. @L is aplan view of one end of the shuttle with my improvements applied; and

Fig. 5 is a cross-sectional View of the threader, taken through the threading portion.

Referring by letter to the said drawings, A indicates a shuttle for looms, which may be of any ordinary or approved construction. This shuttle is provided, near its forward end in one of its side walls, with a slot a, which is preferably of a curvilinear form. l

B indicates a spindle pivoted in the usual manner in one end of the shuttle, as shown.

C indicates the threading-plate. This plate is pivoted near one edge, as at b, in the forward end of the shuttle-body, and the said plate is connected with the heel of the spindle by means of a rod D. The plate C is also provided with a threading -loop d. This 4.5 threading-plate is preferably made of thin metal and laps over the side of the shuttlebody, as better shown in Fig. '-t of the drawings. The pivot?) is arranged at such a point that when said plate has been turned for- Serial No. 317,416. (No model.)

wardly by the action of the spindle and con- 5o necting-rod the threading-loop of the plate will travel in the course of the groove d in the shuttle, so that the thread from the cop or bobbin placed in the threading-loop will be carried to the base of said groove in the shuttle.

E indicates ahorizontal arm, which extends from the inner side of the threading-plate and Inay be made integral therewith. This arm, which assumes a position within or 6o across the forward end of the shuttle, is provided with a beveled or tapering guide-extension e and a lower guard-extension f. The arm is furthermore provided with a passage for the thread, as better shown by dotted lines in Fig. et of the drawings, the thread-passage of the arm being in line with the loop d in the threading-plate O.

By reference to Fig. 5 of the drawings it will be seen that I employ a double plate C 7o F, which t-s over the side of the shuttle-body, one plate C lying inside and the other F outside.

In operation the spindle is first raised in the shuttle, as shown in Fig. l of the drawings, which being connected by the rod D with the threading-plate throws the saine into the position shown in said gure. The operator then takes the thread from the cop and carries it over the hook or guide e, which 8o conveys it to the wayin the arm. The spindle is then turned down, when its threading-plate is thrown forward, and when the thread is tightened it enters the eye of the loop and the shuttle is properly threaded for use.

By the employment of the projection f the thread is prevented from falling beneath the loop or being carried beneath the same.

Having described my invention, what I claim isl. The combination, with a shuttle-body having a thread-receiving slot in one of its forward side walls, of a threading-plate having a threadingloop and pivoted in the shuttle, the spindle, and arod connecting the 95 threading-plate with the spindle, whereby the movements of the spindle will turn the plate on its pivot, substantially as specied.

2. The combination, with a shuttle-body having a curvilinear slot in one of its forward side walls, of the spindle and a plate provided with a threading-loop and pivoted in the shuttle so as to eonduet the thread in the slot of the shuttle, said plate being connected with the spindle, whereby the movements of the latter will operate the threadingplate, substantially as speeied.

3. The combination, with a shuttle-body having a thread-receiving slot in one of its side Walls, of a threading-plate having aninwardly directed branch provided with a thread-passage and also provided with means for guiding the thread, a pivoted spindle, and a rod connecting the plate with the spindle7 substantially as speoied.
